SAND-BAND.

SPECIFICATION forming part of Letters Patent No. 447,287, dated March 3,1891.

. sheet-metal shell, and l) a head made of mal- To all whom it mayconcern:

Be it known that I, ALBERT BALL, a resi dent of Olaremont, in vthecounty of Sullivan and State of New Hampshire, have invented certain newand useful Improvements in Sand- Bands; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and use the same.

The object of the invention is to simplify and cheapen the constructionof sand-bands and of the means of connecting them with an axle of awheeled vehicle.

Heretofore the shells of sand-bands have been provided with an innerinturned flange which was clamped between a screw-threaded nut placedwithin the shell adjacent to the flange and an exieriorly screwthreadedholder fitted on the axle. This holder has been made in the form of amutilated or incomplete ring, being slotted for the reception of theaxle. holder was embraced by the ordinary yoke, which holds together thewooden and metallic sections of the usual form of carriage-axle, and wasthereby clamped to the bottom of the axle. By the present improvementthe inner screw-threaded ring is dispensed with, and the inner endof theshell is provided with a head secured directly thereto by swaging andhaving a screw-threaded opening adapted to screw upon the axle. Theaforesaid holder is provided exteriorly on its main part withscrewthreads, which are continuous with others formed on the axle, uponwhich the interiorly screw-threaded head of the sandband is screwed.

The invention consists in the construction herein described, andparticularly pointed out.

In the drawings, Figure 1 is a partial longitudinal section of sand bandor box. Fig. 2 is a central longitudinal section of a modified form.Fig. 3 is a similar section showing the band applied to the axle. Figs.4, 6, 7, 9, and 10 are like sections of modifications. Fig. 5

is a section of the head shown in place in Fig. 6, and Fig. 8 is a planshowing the interior of sand-box.

Referring to Fig. l, the letterA indicates a An extension or arm ofsaid.

leable metal. This head is provided with a screw-threaded openingadapted to be screwed directly upon the axle, as indicated in Fig. 3. Ithas also at 1 a groove adapted to receive the edge of the shell A. Aftersaid shell has been entered in the groove the metal of the head isforced or swaged upon the shell, so as to hold it tightly, by whichmeans the parts are securely fastened together. By preference the edgeof the sheet-metal shell that enters the groove is folded or rolled uponitself or otherwise slightly enlarged, and the metal of the head is thenforced over and upon this edge, making a strong joint. Figs. 2 and 3show a joint without such enlargement of the shell.

F is an axle-holder, 311611111 are sand-outlets. I am aware that theshell of a sand band or box has been clamped between an interior ringand the holder, and also thatsuch interior ring has been dispensed withand the shell provided with a head soldered thereto, and such devicesare not of my invention, it being characteristic of my improvement thatthe head is made of metal that is malleable or whose rim can be made so,and that it is provided with a groove, ledge, or seat adapted to receivethe edge of the shell by swaging or like means.

As shown in Fig. 4, the shell is provided with an inturned flange O, andthe rim of the head D is made smaller than the form first described.

R is a flange or shoulder, between which and the edge S of the head theflange O is received by forcing the edge S, previously beveled, as shownin Fig. 5, upon the flange.

A similar construction is illustrated in Figs. 6, '7, and 8, theshoulder being located in the exterior of the flange of the shell andthe turned-down edge d on the interior. This edge is preferably cut orslotted at intervals in this and also in other forms of theimprovementto facilitate turning down, swaging, or clinching the same upon theshell or its flange.

In Fig. 9 is shown a form in which a wide groove or channel is formedaround the ring portion D of the head, into which groove is fitted acollar formed on the annular band D.

The annular ridges that form said groove, or one of them, is swaged orforced down upon the edges or edge of the collar in such manner as tosecurely hold or grip it. The outer edge of the band D is united to thelower edge of the shell by a lap-joint. The edge if made continuous canbe expanded and turned outward and down, but not so conveniently as whendivided in sections, as indicated.

In Fig. 9 is shown a modification in which the edge of the shell isexpanded and made to embrace the rim of the head and then forced uponsaid rim to lock them together. The head is preferably made larger thanthe shell just below the expanded part, so that the expansion of theshell partially surrounds the edge of the rim of the head.

T indicates an inturned edge of the sheetmetal shell, the purpose ofwhich is to stiffen the joint.

By the above-described selection of material and suitable constructionof parts I am able to make a joint between the shell and head of asand-box more stable and more economical than by soldering, the edge ofthe shell being simply gripped or pinched between opposing parts of thehead, one of which is forced upon it by use of Well-known means, or insome cases the shell can be made to embrace the edge of the head, asexplained.

I am aware that caps of less diameterthan the hub have been fitted upona rim or head secured upon the axle by means of lugs and notches in theadjoining parts or by means of a close fitting of the parts. By myimprovement the head is made malleable, and a part of it is swaged orforced upon the band.

This band is larger in diameter than the end of the hub and embraces thesame, and is therefore liable to greater strain,'owing to its exposedposition andlargersize, and the locks or the friction devices beforeemployed are insufficient to securely hold the parts in place.

Having thus described my invention, what I desire to secure by LettersPatent is 1. In a sand band or box, a shell provided with a head ofmalleable metal having a groove or its equivalent for the reception ofthe edge of the shell, said edge being gripped by an edge of the metalof the head forced down upon the same, substantially as set forth.

2. In a sand band or box, a shell provided with a head of malleablemetal having a groove or its equivalent for the reception of the edge ofthe shell, said edge being gripped by an edge of the metal of the headforced down upon the same, said edge being slotted or cut in sections,substantially as set forth.

3. In a sand band or box, a shell having a folded or enlarged edge andprovided with a head of malleable metal having a groove or itsequivalent for the reception of the edge of the shell, said edge beinggripped by an edge of the metal of the head forced down upon the same,substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

ALBERT IAIAL.
